Three N-S-trending volcanoes of the Quimsachata chain rise along the Chile-Bolivia border above the SW shore of Laguna Chungará. From left to right, they are 5730-m-high Volcán Humarata, 6052-m-high Volcán Acotango, and 5990-m-high Cerro Capurata volcanoes. No historical eruptions are known from the chain, but Acotango volcano has a youthful morphology with lava flows of inferred late-Pleistocene age. Its broad summit crater is open to the north and is the source of a large andesitic-dacitic lava flow.
